    Ideal Gas Law….?


    I am working with an inert atmosphere tube furnace that uses hydrogen gas.
    There is a constant flow rate of hydrogen and I am wondering how to calculate how long a cylinder of hydrogen will last.

    Cylinder= 100 Liters
    Flow rate= 20 cubic feet / hour
    Temperature in furnace= 1300 C

    Is this all of the information I need to calculate how long the cylinder of gas will last flowing at 20 cubic feet per hour?
    I appreciate the help

    you need the volume and pressure in the cylinder.

    Is the H2 burnt off at ambient pressure? Use the PV ratio for your approximation.
